Re: [Xen-devel] [PATCH v3 03/26] ARM: GICv3 ITS: allocate device and collection table



Hi Andre,

Each ITS maps a pair of a DeviceID (for instance derived from a PCI
b/d/f triplet) and an EventID (the MSI payload or interrupt ID) to a
pair of LPI number and collection ID, which points to the target CPU.
This mapping is stored in the device and collection tables, which software
has to provide for the ITS to use.
Allocate the required memory and hand it to the ITS.
The maximum number of devices is limited to a compile-time constant
exposed in Kconfig.
